Answer:
When you have to get these measurements completely then you apply some multiplication as follows: Calculate cubic feet for different units (formula) From feet: length (ft) × width (ft) × height (ft) = cubic feet From inches: length (in) × width (in) × height (in) ÷ 1728 = cubic feet
Step-by-step explanation:
I don't know, sorry
Answer:
B
Step-by-step explanation:
You cant find the square root of ten. It is a decimal that keeps on repeating. Therefore, it is irrational.
"The difference of" means subtraction
"of 5 times a number" means 5N
"and twice that number" means 2N
So the statement is the subtraction of 5N and 2N
5N - 2N
The second option is correct.
Answer:
The nearest degree of the angle between the 8cm and 9cm sides is:
Step-by-step explanation:
To obtain the correct angle in a small triangle like the triangle formed with the measures in the exercise is a little bit hard, in a change of this, I used a triangle calculator, with this I obtained the right angle formed by the sides with 8 cm and 9 cm, which I'm gonna add like an attachment.
From this image, you can guide yourself to draw the triangle without mistakes and to identify the right angle, which is 40,8° but the compass is not so defined, by this reason you can take it like 41° or 40°.
In this question, you're solving the systems of equations to find what x and y equal to.
Solve the systems of equations:
x + y = 3
x + 2y = 6
Lets make the "y" variable the same by multiplying the top equation by -2.
-2(x + y = 3)
x + 2y = 6
----------------
-2x -2y = -6
x + 2y = 6
Solve:
-x =0
x = 0
Now, we know x = 0, now plug 0 into x in one of the equations and solve:
We'll plug it into the x + y = 3 equation.
0 + y = 3
y = 3
When you're done solving, you should get:
x = 0 and y = 3
Answer:
x = 0
y = 3
